It has application to electronic machines and agendas, calculators, mobile telephones and to any communication equipment, offering a distribution of the keys which facilitates and simplifies the handling of these apparatus. There exist twenty basic keys distributed in five rows and four columns, the five vowels being arranged in the first of the columns and without being accompanied by any further letters. The remaining letters, the consonants, are also assigned an independent key apart from those occupying the lower part of the two inner columns, which have two letters. This distribution is more rational on account of its simplicity of location and follows the same order of known keys, in other words, the order of the entire alphabet is not changed. The numbers are arranged in the known form in the upper part of the first three columns and in the lower part the symbols used for different applications can be located. <IMAGE> |
